What does refractory to treatment mean?
Listen to pronunciation. (reh-FRAK-tor-ee) In medicine, describes a disease or condition that does not respond to treatment.
Why nanomedicine is preferred over conventional medicine?
Nanomedicine is holding promising changes in clinical practice by the introduction of novel medicines for both diagnosis and treatment, having enabled to address unmet medical needs, by (i) integrating effective molecules that otherwise could not be used because of their high toxicity (e.g., Mepact), (ii) exploiting …
Does nanotechnology exist?
Although modern nanoscience and nanotechnology are quite new, nanoscale materials were used for centuries. Alternate-sized gold and silver particles created colors in the stained glass windows of medieval churches hundreds of years ago.
What does relapsed or refractory mean?
The term “relapsed” refers to disease that reappears or grows again after a period of remission. The term “refractory” is used to describe when the lymphoma does not respond to treatment (meaning that the cancer cells continue to grow) or when the response to treatment does not last very long.
Can nanotechnology be used as a weapon?
The use of nanotechnology thus enables existing weapon technologies – such as stealth, precision-guided munitions and UAVs – to evolve into their ultimate form. It will provide soldiers with the ultimate protection of invisibility during combat operations or intelligence, surveillance and reconnaissance activities.
Is nanotechnology a metal?
Metal nanoparticles are submicron scale entities made of pure metals (e.g., gold, platinum, silver, titanium, zinc, cerium, iron, and thallium) or their compounds (e.g., oxides, hydroxides, sulfides, phosphates, fluorides, and chlorides) [44,45].
What is refractory ALL?
Some patients have residual leukemia cells in their bone marrow even after they receive intensive treatment. In these cases, the disease is referred to as being “refractory” (or “refractory ALL”).
How does nanoparticle drug delivery work?
Through the manipulation of size, surface characteristics and material used, the nanoparticles can be developed into smart systems, encasing therapeutic and imaging agents as well as bearing stealth property. Further, these systems can deliver drug to specific tissues and provide controlled release therapy.
Can nanobots be used for mind control?
A man has used thought alone to control nanorobots inside a living creature for the first time. The technology released a drug inside cockroaches in response to the man’s brain activity – a technique that may be useful for treating brain disorders such as schizophrenia and ADHD.
What is a refractory?
Refractories can be defined as the ‘non-metallic materials having those chemical and physical properties that make them applicable for structures or as components of systems that are exposed to environments above 538 °C′ [1].
What is the application of nanotechnology in refractory materials?
The objective for the application of nanotechnology in refractories is to improve the compressive strength, tensile strength, ductility, resistance to thermal shock, abrasion and chemical corrosion, aggregate-paste bond strength, ability to control of cracks and self healing, etc [9], [10], [11].
What is nanotechnology in science?
What Is Nanotechnology? Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Physicist Richard Feynman, the father of nanotechnology. Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields,
What is the impact of nano-scaled materials on castable refractories?
The addition of nano scaled materials in castable compositions generally creates a positive impact in the process of making castable refractories. Nano powders occupy the voids between castable aggregates, promote coursing of particles during sintering, and consequently, reduce the sintering temperature.
